I purchased an SMHUB ESSENTIAL and configured it as a controller for a Zigbee network, a Zigbee2MQTT network, and a Z-Wave network. I had some trouble configuring it, but thanks to the endless patience of SMLIGHT's technical support, I finally got it working. I was able to replace three separate antennas for the three networks with a single device, which is also PoE-enabled, allowing me to plug it into an Ethernet port.
